I am scared.. I am 18.. I have a lump on the very tip of the glans on the right side of the erithra, I am worried it could be penile canser.. My frend told me that she watched a show about some teenager, and he had a lump on his penis, and he was worried, so he went to the doctor and the doc told him it was because of masterbating to much, I have been masterbating 2 times a day for a looooong time, and there was a while were I was doing it 3 times a day.. I am worryed that it might be cancer, because 2-3 times a day doesnt seem like much is small.. and it was their like 2 years ago.. and I stoped masterbating for awhile and it seemed like (form what I can remeber but I am not sure that its intirly true) that it went away, and ever since I started talking to this one girl its been like masterbating 2-3 times a night... and you can barely notice it unless you look REALLY carefully.. and its not hard or anything, it feels like the rest of the glans.. so I dont know.. when I get an erection it gets bigger, there is this wierd dot right next to it, (like if it were anywhere else I would say its a TINY mole, but since its on the glans, I dont think its possible to get a mole on the glans of your penis :s) I feel like an fool talking about masterbating, but I masterbated this morning. and on the right side of the head it has been tingling.... but jsut for this morning.... please respond.. I am really worried
